无法在ubuntu中为golang编译原始文件

Question

I've installed these packages:

google.golang.org/grpc

github.com/golang/protobuf/protoc-gen-go

and exported path like this:

export PATH=$PATH:/usr/local/go/bin

when I try compile proto file with protoc command, I see command not found error:

protoc --go_out=. helloworld/helloworld.proto 

zsh: command not found: protoc

my project path is like: /home/my-username/go/src/github.com/my-username/helloworld

my go version: go1.12.5

and I use ubuntu 18.04

When I install it with binary file it works, but compiled go file does not contain some functions like: RegisterGreeterServer or NewGreeterClient

Answer 1

Finally with help of Amit, I installed protoc. but when I compiled proto file with this command

protoc --go_out=. add/add.proto    

go compiled file did not contain some functions like: RegisterGreeterServer or NewGreeterClient for instance.

by this reply I found out issue and added plugins=grpc, then tried this command and it worked:

protoc --go_out=plugins=grpc:. add/add.proto
